The GeForce GT 755M Mac Edition was a mobile graphics chip by NVIDIA, launched on November 8th, 2013. Built on the 28 nm process, and based on the GK107 graphics processor, in its GT 755M variant, the chip supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GK107 graphics processor is an average sized chip with a die area of 118 mm² and 1,270 million transistors. It features 384 shading units, 32 texture mapping units, and 16 ROPs. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GT 755M Mac Edition, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1085 MHz, which can be boosted up to 1085 MHz, memory is running at 1250 MHz (5 Gbps effective). Being a mxm module card, the NVIDIA GeForce GT 755M Mac Edition does not require any additional power connector, its power draw is rated at 50 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. GeForce GT 755M Mac Edition is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
